There comes a time in life when no night passes without the inevitable trip to the bathroom. Boys, however grown-up they may be, are incapable of manipulating a loo seat. They may pride themselves on their legendary special awareness, but that space doesn’t for some bizarre reason, extend to the loo seat. No matter. The Lav Nav is a night-time traffic light for the loo seat. Red = Seat Up, & Green = Seat Down. Being motion sensitive, it will light up on your approach, not only guiding you to the loo, but letting you know whether the loo seat is up or down. However groggy or bleary eyed you are, the Lav Nav will be your sentinel, so to speak.
